Q. When I reach 59½, can I withdraw my full TSP without a penalty if I still work my federal job until I reach 62?
A. You may take an age-based, in-service withdrawal from your vested account balance once you reach age 59½. You may withdraw your entire vested account balance at that time. Once you reach age 59½, you are exempt from the early withdrawal penalty in any case. Use form TSP-75 to request the withdrawal.
